A Multicenter Evaluation of a Compact, Sterile, Single-Use Pressure Transducer for Central Venous Catheter Placement

Abstract

The Compass pressure transducer for CVC placement performed as intended in 298 cases from 4 academic medical centers. There were 5 inadvertent arterial punctures despite the use of ultrasound guidance, all of which were correctly identified by pressure measurement using the Compass. The device was easily used by trainees, and users expressed a positive level of satisfaction.
